Running Lab: Training Your Running CadenceModifying your running technique can be an effective prevention and treatment tool. Recent research has focused on reducing impact forces at the knee through altering running biomechanics. Increasing step rate by 5% reduces the mechanical energy at the knee by an astounding 20%. In theory, increasing cadence shortens the stride. Biomechanically, a shorter stride leads to a foot strike closer to your center of mass thus reducing the impact forces at the knee.
